In a large baking dish, combine the halved cherry tomatoes, minced garlic, and olive oil. Season with salt, pepper, oregano, and red pepper flakes; mix well.
Make a well in the center of the tomato mixture and place the feta cheese block in it. Drizzle a little olive oil on top of the feta.
Bake in the preheated oven for 25-30 minutes or until the tomatoes are blistered, and the feta is golden and soft.
While the feta and tomatoes bake, cook the orzo according to package instructions until al dente. Drain and set aside.
Once the feta and tomatoes are done, remove the baking dish from the oven. Using a fork, mash the feta into the tomatoes and stir to combine.
Soon after, add the cooked orzo to the feta-tomato mixture and stir well until everything is evenly coated.
Adjust seasoning if needed and serve hot, garnished with fresh basil leaves.
Notes
Adjust red pepper flakes to taste for desired spice level.
